People leaving care will now be able to use buses across the west of England for free until they turn 26 years old.
Since 2023, a scheme has been in place allowing 18-21-year-old care leavers free bus travel across Bath, Bristol, North Somerset and South Gloucestershire.
This has now been extended to cover care leavers until their 26th birthday, which could save each of them up to £1,050 a year, according to the West of England Combined Authority (Weca).
"We've got many more care leavers at risk of homelessness, health, addiction or mental health issues so this is really important," said Weca's mayor.
Helen Godwin used to be a cabinet member for children's services at Bristol City Council, before she was elected as Weca mayor on 1 May.
She explained care leavers "often don't have the same outcomes" as young people who have not been in care.
